You armed with whatever have been watching mr gunman and mother fight for some time not doing nothing because it was none of your biz. mr gunman also starts threatening mr philipines and yet you still do nothing. then mr gunman points the gun at you you kick his ass and mr philipine(he has a kick ass pool that you want to use even though he says no) and then start threatening Mother(china) and eventually start conflicts with them as well.(aka the korean war)
In case you still don't understand the concept of "we saved China's ass" in WWII, let me elaborate with an analogy:
You, armed w/a kevlar vest, jump in front of a bullet aimed into a crowd mainly because the gunman is aiming at your MOTHER. You stop the bullet, knowing you're going to save both your mother AND a few other pedestrians (assume bullet is super powerful). After u save ur mother, you find out you saved 3 others right along with her.
Now, do you walk up to the hero later and say, "You didn't "save" the bystanders!" (CHINA, Phillipines, etc.) even though without the hero's help, they bystanders (CHINA, Phillipines) would be DEAD.
